-0.3x=1.9-0.4
Tangohia te 0.4 mai i ngā taha e rua.
-0.3x=1.5
Tangohia te 0.4 i te 1.9, ka 1.5.
x=\frac{1.5}{-0.3}
Whakawehea ngā taha e rua ki te -0.3.
x=\frac{15}{-3}
Whakarohaina te \frac{1.5}{-0.3} mā te whakarea i te taurunga me te tauraro ki te 10.
x=-5
Whakawehea te 15 ki te -3, kia riro ko -5.
